Integer to String conversion in java

Question

I'm learning to work on strings in java. This is a code I got from an online source.

int i = 5;
String strI = "" + i;

I'm not familiar with Java. Is this the way to convert int to string or its just and unorthodox way to do so ?

Answer 1

int i = 5;
String strI = "" + i;

Although the above mentioned method does convert an integer to string but there are other ways too for doing the same task:

1. int i = 5;

   String strI = Integer.toString(i); #Converts an integer to string

2. int i = 5;

   String strI = String.valueOf(i); #Gets a string representation of an object (integer)

Answer 2

We can do this in 2 ways:

String strI = String.valueOf(i);
String string = Integer.toString(i);
